Oh capsicin my capsicin
"Perhaps the single most wonderful and most beneficial herb in the entire herbal kingdom is Capsicum, or Cayenne Red Pepper. Many herbalists have said that if they could have only one herb to work with, they would choose Capsicum.
Cayenne is a pepper well known for its benefits to the circulatory system. It aids the body to balance pressure levels and resist abnormal bleeding. Cayenne is also used as an overall digestive aid: It stimulates the production of gastric juices, improves metabolism, and even helps relieve gas. It appears to have a beneficial effect on blood fats as well. This plant assists in the body's utilization of other herbs, when used in an herbal combination. When applied topically, it helps relieve minor discomfort.
According to a 1987 study published in the Journal of Bioscience, rats fed a diet high in cayenne experienced a significant reduction in blood triglycerides and low density lipoproteins (LDL), or "bad" cholesterol. Capsicin, a compound found in cayenne that gives the spice its "kick," is an anti inflammatory.
Recently, cayenne has been used successfully to treat patients with cluster headaches, a particularly painful type of headache. Used externally, cayenne liniment can soothe the stiffness and pain of rheumatism and arthritis.
Cayenne will work nicely as a general immune booster, or as an addition to treatment of almost any ailment.
